skill points (in the tama-meter thingo.. after training)
are just points you can earn by different foods and different games
that determine what job you will get when your tama is an adult and what it will evolve into when its an adult.
the skills include.. intellectual/arts/social
intellectual is shown by a pencil
arts = a star
social = a flower
for example
if your tama was a teen, and you have 60 intellectual points (you can check on the tama-meter menu, press A 2 times) and you only have 10 arts and 10 social, then your tama will turn into an intellectual tamagotchi. (look at growth charts to see which is which..)
if you have more problems, dont be afraid to ask =]
hope this helped... (sorry if its confusing.)
